Boundary Asymptotic Analysis for an Incompressible Viscous Flow: Navier Wall Laws

Boundary Asymptotic Analysis for an Incompressible Viscous Flow: Navier Wall Laws We consider a new way of establishing Navier wall laws. Considering a bounded domain Ω of R N , N =2,3, surrounded by a thin layer Σ ε , along a part Γ 2 of its boundary ∂ Ω, we consider a Navier-Stokes flow in Ω∪ ∂ Ω∪Σ ε with Reynolds’ number of order 1/ ε in Σ ε . Using Γ-convergence arguments, we describe the asymptotic behaviour of the solution of this problem and get a general Navier law involving a matrix of Borel measures having the same support contained in the interface Γ 2 . We then consider two special cases where we characterize this matrix of measures. As a further application, we consider an optimal control problem within this context. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Mathematics and Optimization Springer Journals

Abstract

We consider a new way of establishing Navier wall laws. Considering a bounded domain Ω of R N , N =2,3, surrounded by a thin layer Σ ε , along a part Γ 2 of its boundary ∂ Ω, we consider a Navier-Stokes flow in Ω∪ ∂ Ω∪Σ ε with Reynolds’ number of order 1/ ε in Σ ε . Using Γ-convergence arguments, we describe the asymptotic behaviour of the solution of this problem and get a general Navier law involving a matrix of Borel measures having the same support contained in the interface Γ 2 . We then consider two special cases where we characterize this matrix of measures. As a further application, we consider an optimal control problem within this context.
